Alpha Inverter Module 1500 provides pure sine wave power to critical loads despite power disturbances such as harmonics, surges, glitches, voltage fluctuations, etc. Unlike traditional inverters, the Alpha Inverter features AC-AC conversion that double filters and isolates the AC input, and static switching for disturbance free transfers between input sources. The overall efficiency is increased to 93% without compromising the quality and stability of the output wave form. The modular design allows gradually incrementing the system capacity as the load demands increase up to 24kVA.
